Abstract: PURPOSE:To obtain superior monochromatic light whose wavelength is variable with less distortion and spontaneously emitted light by a method wherein an external oscillator is arranged on the output optical-path side and a band-path filter is rotatably arranged within a parallel optical-path so as to improve the oscillator efficiency. CONSTITUTION:A high reflectance film 9 is deposited on the non-output side of a semiconductor laser 1, an antirefection film 8 is deposited on the output side. An external oscillator is comprised of a collimating lens 2 which turns the stimulated emission light emitted from the antireflection film 8 into a parallel beam, a collimating lens 5 which focuses the parallel beam on the input end surface of the optical fiber 7, and a partial reflection mirror 4 deposited on this input end surface.

In addition to that, a stability against external vibration and misalignment is provided since the partial reflection mirror 4 is deposited on the focus section without reflected light from the other surface of the reflection mirror. Thus, it is possible to variably obtain a superior monochromatic light whose wavelength is variable with less distortion, etc., with improved oscillation efficiency.
